CLAMP SNAP.

'Application led February 14, 1923. Serial No. 618,915.

The invention is a `snap with prongs pro-l j ecting from its members bywhich it may be clamped tothe goods instead of being sewn.

The object of the invention is to provide a snap, the sections of whichhave points projecting from them that maybe pushed through the goods andthen bent over to clamp the snaps in place.

Another object of the invention is to providev a snap that may instantlybe applied to the goods. 'v

And a further object of the invention is to provide a snap that may havesections in the shape of points punched from it which sections may bebent back to clamp the snap to a piece of goods.

With these ends in view the invention embodies a snap the two sectionsof which are made with points projecting from them which may be bentdown to clamp the snaps to the goods.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings, whereinFigure 1 is a cross section through the upper section of the snap.

Figure 2 is a plan view of the upper section.

Figure 3 is a cross section of the lower section.

Figure 4 is a plan view'of the lower section.

Figure 5 is a section showing the snaps on goods and snapped together.

In the drawings I have shown my snap as it would be constructed whereinnumeral 1 indicates the upper section and numeral 2 the lower section.The upper section may be constructed as shown with an opening 3 in itscenter similar to that of a standard snap which receives the projectionon the lower section; and points 4 projecting updesign.

points 4 may be forced through the goods and then bent downward againstthe body of the section so that the goods maybe clamped between themandthe section. It

will also be seen that ifdesired these points may be made 'very narrowso that they mai; be forced through the goods without cutting orbreaking the threads. l

The lower section shown in Figure 3 may be made as shown with points 7similar to the points 4 of the upper section stamped from the openings 8in the body of the section as shown in Figure 4 or from additionalmaterial as indicated by the dotted lines 9. These points may also be ofany Suitable shape or length as described for the points on the uppersection. j

'I he snaps may be furnished with the points projecting straightbackward as shown. Y

It will be understood that changes may be made in the constructionwithout departing from the spirit of the invention.

of points used as it is understood that any either the upper or lowersection. Another change may be in the design of the body of either ofthe sections as it is understood that the points may be used on 'snapsof any The construction will be readily understood from the foregoingdescription. To use the device it may be furnished as shown and' it willbe seen that as the points are placed against the goods they will forcetheir iway through it and after the `goods are firmly against the' bodyof ,the section the points may be bent downward against the goods, thusbinding the 'material between the inner surfaces of' the prongs and theupper surface ofthe ridge formed bythe edge of the snap from which theprongs project. It will be seen that they will positively hold thesections'to the goods and it will also be seen that the snaps may bestamped onto the goods by a small machine or other automatic means andit will there` fore be possible to run a piece of goods vthrough amachineand have it come out with the snaps in place.

Having thus fully described the invention,

what I claim as new and desire to secure by Letters Patent, is

Y One of these changes may be in the number In affastening device, twocircular memits outer edge with points extending perbers, means forsnapping one member into pendicularly from the outer edge of the theother, one 0f the said members being said iange, the inner edge of thesaid curved 10 iatand having points extending perpenfiange forming abinding ridge so that ma` 5 dicularly from its base, andthe other ofterial may be gripped between it and the inthe said members having itsbody portion ner sides of the said points. l curved and having a curvedfiange around ROSE D.
